Why is everybody using such big air cpu coolers?

Recommended Posts

There's nothing wrong with small coolers. Not even when you decide to OC. Budget coolers like 212 and Pure Rock are just fine for small OC. The main reason why you see so many bigger coolers for higher end builds is because question which is asked goes "what is best air cooler". There are only so many answers and none of them is small.

 

I picked my current because price difference with U12S was like 10e. And because I like Noctua and U9B before. I looked other coolers like be Quiet! and Xigmatek ones, but difference with cooling performance, price and noise was all for Noctua. If I could repick right now, it would still be Noctua. But possibly either U12S or C14. Because I want more options on picking case. Not easy to find cases with 165mm clearance.

Since I planned my transition from Mac Pro to Custom Pc, I've thought a lot about what cpu cooler to use. Amongst the rather unknown and unfelt AiO surge, I would still rather cling to air coolers, as there is no liquid involved. However, it is more than obvious, especially with builds similar to mine, that there are no small coolers involved. Everybody straps on either a Noctua 15s, or Dark Rock 3, which leads to "I buy whatever is the biggest and most expensive". I do get that mostly overclocking is involved, but am I the only person who does not want to overclock their cpu for now? 

 

It's a legacy thing, similar to what happens with high wattage PSUs (something LTT's video omitted): computers used to get faster, hotter, and more power hungry over time. I remember a PSU advertising compatibility with 10-pin GPU connectors in case they ever were released for "futureproofness". Of course, that never happened, because at some point GPUs started to be more powerful while using less current.

Similarly, CPU coolers kept getting beefier over time, as CPUs became more demanding, running more cores at higher speeds. But at some point power efficiently improved faster than speed, leading to decreases in TDP as new CPUs were released. And just like you may still feel inclined to buy a 1200W PSU for SLI or whatever, and it won't really hurt you (unless you really have a low power system, due to efficiency losses) other than in the wallet, you can also strap the same cooler you used to overclock your 140W CPU into a modern 7X-8X W CPU at stock speeds and it won't hurt you, it's just overkill.

Intel's mainstream line will probably run dead-silent at stock speeds on a $40 heatsink; overclocking is a different story.

They pretty much have to be at least 120mm or 140mm to support a fan... so... they will always at least be that big if you want one that a normal pc fan can fit.

Not really, they could use smaller fans as many coolers do (92mm, 80mm, 60mm as many stock coolers, etc).

I said that here... (below) he was mostly asking about big cpu coolers though anyways and most big coolers use 120mm or 140mm.

Stock and SFF options are usually smaller and usually horizontal, but those don't fall under the category of the "why is everyone using such big cpu air coolers" thread title.

Alright, so I've tried the NS-12 on my 6900k and I gotta say that the temperature is a tad high for my taste, especially according to the socket, which is without OC (stock self OC to 3.7 GHz) at 84 degrees. I think if I deactivated Max Turbo Frequency would be a lot less, maybe 70 at max? Anyways, for what it is right now, the 6900k, I think I'd benefit from a corsair h115 a lot or go with the biggest Noctua available, but that would only give me another headstart of 5 degrees room to where I am right now. Probably, for the 8 core, that turbo boost to 3.7 is not doable with turbo boost 3.0.

i use both an nhu12s as well as a nhd15s

I also can run an OCed (not full load) i7 passively with the nhd15 for most the time. 


Silverstone FT-05: 8 Broadwell Xeon (6900k soon), Asus X99 A, Asus GTX 1070, 1tb Samsung 850 pro, NH-D15

 

Resist!

This is what I'm getting with my 6900k at stock clock, turbo-boost deactivated and prime 95 during the first test after 2 hours:

Are these temperatures good or would I benefit from the d15s? I mean, just getting 5 degrees better temps wouldn't make it worth the swap in my case. I also have a Corsair 115i lying around, with which I still don't know how to proceed, for whether I'd either install or send it back.

Yes, those temps are good--not sure why you turned off turbo boost though.

Im going to use cryorig h7 on my new build , is that big ? its one of the cheapest i could find for 2011. Didnt want to buy hyper 212 its overused and ugly.

You could look at the measurements listed on the manufacturer website. Whether it's big or not depends on who you're asking.

Will they serve me well in terms of long durability for at least 5 years?

 

Deactivated because I was getting 80 degrees on the socket (package).

 

By the way, prime 95 says unknown intel cpu and unable to detect some of the hyperthreaded logical cpus.

If you keep temps below ~85c at load and don't push high voltages, your cpu should easily last at least 10-20 years.

That sounds like an issue with Prime95. Have you tried reinstalling it?

Well, I've downloaded a self-contained executable, there was no installation, just launching the .exe and yeah I've redownloaded the current version with no change. Does it mean it might not have been properly stressed? Don't think so right?

 

No, I just want to run it at stock speeds, or do you think I would benefit from the d15s? Don't think so either at stock right? Other than maybe 5 degrees less in stock? Funny enough, in stock, it only draws 100 watts, which is actually not that bad, temps could be better for such a power draw though? During turbo-mode, it hits 155 watts.

I personally use OCCT. I wouldn't worry about Prime95 not recognizing the cpu unless you bought it from someplace sketchy. 

Turbo boost comes stock with the cpu and there's little reason to turn it off unless the power draw is an issue. 

Your temps are already low and getting them lower won't do anything for you.

Uhm I bought it from a guy on ebay but it appears to be all fine, it just had some thermal paste on the pins I cleaned with 99.9% isopropanol. What do you mean by sketchy?

By sketchy, I meant a seller that isn't trustworthy or reliable.

Yeah but you mean in terms of broken cpu? I mean, it runs fine in prime 95  with no errors after 4 hours. He sold others before as well.

I got the PM. Like I said, don't worry about it unless you think you bought your cpu from someplace sketchy. 

If the seller has been reputable and your cpu is working fine, don't fret.

Well except I have no idea what good temps are nowadays, that's why I've aksed. Last time I put pcs together was in 2007. I remember a little bit before my Q6600, which was the last cpu I put in a windows system, I had owned an AMD 64 FX processor, that thing constantly shut down due to critical temps, even though I had zalman on, and no OC :D Good times.

So picking up the d15s wouldn't make too much sense would it? I'd probably not gain much better temps, unless I went with an AiO? But you're saying the temps are good?

Oh btw, with the noctua coolers, I probably don't have to worry about tightening it up too strong because it is protected by the springs? So I can't pull it too tight?

You should be fine. I've turned them extremely tightly in the past without any issues.

Oh that's good, because usually, after I've reached the end point, I usually insert the screwdriver once more to see if it can be tightened a little bit more. So that's fine?

 

Oh, I had it running once more in prime 95 under the first test for 5 hours with the following results:
